Weighted Hula Hoops from Canyon are the only custom hoops that use a heavy duty 200-250 psi polyethylene tubing for our exercise hoops. No amount of normal use will cause the hoop to kink, crack, bend, or crush. Our Weighted Exercise Hoops have been designed to combine the ideal size and weight to help you lose weight, trim your waist line, build stamina, and improve your overall fitness level. Adult hoops are larger and heavier than kid's hoops for a reason. You need a hoop that fits your current age, energy level and body size. The small adult 38 inch diameter hoop is ideal for smaller body types and teens and the 42 inch hoop is designed for normal to larger body types. The large size and weight make these hoops easy to initiate and maintain the hooping rotation. Have Fun! Get fit! Get Hooping!
